Computer scientists (and any self-respecting scientists) HAVE to separate their ethics from the interests of state institutions.
Why?
The paper argues exactly to the opposite in the first part, describing the atomic-bomb scientists, and the Russell-Einstein Manifesto.In my opinion, cryptographers and computer scientists have ignored morally questioning their work for too long. Reality is now catching up on this, with techniques for surveillance. The paper argues this for cryptography, in my view this is even more generally applicable.
No one else understands the implications of an experiment or a new methodology. I was at a meeting recently discussing ethics committees for computer science. A medical expert gave his opinion and said (paraphrasing): I fail to see the problem with digitalisation, we have had medical records on paper for years, now they are on a computer, what is the difference?
I don't mean to say that every scientist should do this individually. They should discuss this with colleagues, and with an ethics committee, which should contain subject matter experts, but also ethicists.
